Improved sail-hank



UNITED STATES PATENT OEEICEO CHARLES ELLIS, OF GLOUCESTER, MASSACHUSETTS, ASSIGNOR TO HIM- SELF AND DANIEL DOUGLASS, 3D, OF SAME PLAGE.

IMPROVED SAILHANK.

Specification forming part of Letters Patent No. 38,445, dated May 5, 1863.

To all whom t may concern:

Be it known that I, CHARLES ELLIS, a resident of Gloucester, in the county of Essex and State of Massachusetts, have invented an lmproved Sail-Hank; and I do hereby declare the same to be fully described in the following specification and represented in the aecompa-nyin g drawings, of which- Figure l is a top view, and Fig. 2 a transverse'secticn of it.

The nature of my invention consists of a sail-bank provided with two ranges of frietion-rollers arranged within it, in manner substantially as hereinafter described.

I am aware that it is not new to apply one or more i'rictionrollers in a single row to a sail-bank or mast-strap for the purpose of easing a. sail while being either raised or 10W- ered. There is, however, a ditlculty attendant on such a sail-bank, or such an application of the single range of rollers, as they allow the hank to incline more or less from a horizontal position while the sail may be in the act of being either set or lowered. This inclination causes the hank at or near its crotch or angle to bind closely against the mast and so hung to it as to frequently materially impede the raising or falling of the sail, and besides it creates wear of the stay as well as of the hank.

In carrying out my invention I arrange in the hank two rows or ranges of friction-rollers, and so that one of such rows shall be directly over the other, they being xed on a frame screwed or fastened in the curve of the hank. These two :rows of such rollers, being disposed as shown in Figs. l and 2, wherein A is the hank, B B B and O C G the two ranges of friction-rollers, and D the fra-me for holding them. They will maintain the hank square or at right angles to the mast while such hank may be in the act of being either raised or lowered thereon; consequently this will prevent the difficulty above mentioned, which is liable to result when a single range of rollers is employed.

What I claim, therefore, as my invention 1s The combination and arrangement of the sail-bank and the two sets or ranges of friction-rollers, in manner and so as to operate substantially as described.

CHARLES ELLIS.
